Default Buying round bar

Where are good places to buy round bar. Mild steel and up to 2" diameter. I want some pieces to play with and also need to remake a vise screw.

Do you know anyone running a crushing spread, where ever there are crushers and conveyors running there will be used and abused shafting laying around.

One place to go is to a shaft and tube supplier. They will always have drops from cutting to order. I got a 45 gallon drum full of DOM drops for $300, for example. Scrapyards are another source of hot and cold ground shafting.

I get most of mine from auctions.

ORF,

Have you got any hydraulic cylinder repair shops near you?

If so ask if you can have a look in their scrap. Plenty of round stuff will be waiting for you to re-home it

There are two main types of cylinder shafting; CPO, short for Chrome and Polish Only; and IHCP (Induction Hardened and Chrome Plated). CPO is usually 1045 shafting which is excellent to machine. IHCP is most often 4140/4340 (which is also fine to machine) but it has a hardened outer skin .050"-.060" thick which is very tough and almost unmachinable. If your lathe is solid enough to peel off .080"-.100" in one pass it's not bad to work with once you get past that first layer.

If you're looking at used chromed shafting take a hammer with you and give each piece a light tap. It doesn't take much to put a little dent in CPO but you've got to whack IHCP pretty solidly to make a mark. If you have a piece of both you'll quickly see the difference...

I don't know why I didn't think about it before but I think truck axle shafts would work too. The junk yard I got some steel beams from a month ago sells pull yourself auto parts at $0.25 a lb.

Would that only be hardened on each end ie spline and bearing journal?

Truck axles aren't so much hard as they are tough. They're designed to take high torsional loads without yielding--somewhat like a spring. You really have to torque them up before they'll actually twist. They're generally tough to machine and, of course they're unknownium so they're useless for most projects...

If you just got to have it and can't find it anywhere else, www.Metalsdepot.com can help. I found them cheaper than other online sellers.
